This product is compact and space-saving, designed to effectively increase water flow compared to traditional models. It offers higher performance and reliability than conventional float valves and can replace standard floating ball valves with stable operation and durable construction. Made from food-grade 304 stainless steel, this water level control float valve ensures the safety of drinking water. It features a sleek design and a hard-shell body that provides strong resistance to friction and impact, enhancing product longevity and durability. Constructed entirely from stainless steel, the valve operates automatically based on water level changes. When the water level in the tank drops, the float descends, allowing water pressure to open the plunger with a silicone sealing surface inside the valve body, initiating water supply. As the water level rises, the float lifts, and the connecting rod actuates the plunger to shut off the flow. Available in four models: A, B, C, and D. Suitable for use in water tanks, water towers, pools, solar water heaters, and storage systems. No electricity required—operates using clean water with a minimum pressure of 0.2 kg.
